You need to look at what ITA Matrix calls "Fare construction". Look for something like this:
Fare Construction (can be useful to travel agents)
LAX DL JFK 525.58SA0NX0MP DL LAX 386.05QA3NX0MP USD 911.63 END ZP LAX JFK XT 68.37US 8.00ZP 11.20AY 9.00XF LAX4.50 JFK4.50
In this example, SA0NX0MP and QA3NX0MP are the two fares for this particular trip.
When a fare has a code appended with a slash, that's called a "ticket designator". A made up example: SA0NX0MP/XX123 and QA3NX0MP/XX123. In this made up example, XX123 would be the ticket designator.
A corporate ticket designator is appended to fares when there is a discount arrangement between the company and DL.
